Application:
Manufacturing of structural ceramic components: such as balls and rollers of rolling bearings, sliding bearings, sleeves, valves, and structural components with requirements for wear resistance, high temperature resistance, and corrosion resistance, as well as rocket nozzles;
Surface treatment of metals and other materials: alloys such as molds, cutting tools, turbine blades, turbine rotors, and cylinder inner wall coatings;
Composite materials: such as metal, ceramic, and graphite based composite materials, rubber, plastics, coatings, adhesives, and other polymer based composite materials;
Wear-resistant self-lubricating nanoparticle film, used for surface protection of mobile phones, advanced automobiles, etc., as an additive for wear-resistant coatings and electrophoretic paints, with high wear resistance characteristics.
Release agent for quartz crucibles
